Karaite Judaism emerged in the ninth century in the Islamic Middle East as an alternative to the rabbinic Judaism of the Jewish majority. Karaites reject the underlying assumption of rabbinic Judaism, namely, that Jewish practice is to be based on two divinely revealed Torahs, a written one, embodied in the Five Books of Moses, and an oral one, eventually written down in rabbinic literature. Karaites accept as authoritative only the Written Torah, as they understand it, and their form of Judaism therefore differs greatly from that of most Jews. Despite its permanent minority status, Karaism has been an integral part of the Jewish people continuously for twelve centuries. It has contributed greatly to Jewish cultural achievements, while providing a powerful intellectual challenge to the majority form of Judaism. This book is the first to present a comprehensive overview of the entire story of Karaite Judaism: its unclear origins; a Golden Age of Karaism in the Land of Israel; migrations through the centuries; Karaites in the Holocaust; unique Jewish religious practices, beliefs, and philosophy; biblical exegesis and literary accomplishments; polemics and historiography; and the present-day revival of the Karaite community in the State of Israel.

Journeys of the Soul: Concepts and Imageries of Paradise in Medieval Kabbalah covers the most decisive period in the history of Jewish speculation about the Garden of Eden. At the heart of the book is a thorough analysis of the compositions written by medieval kabbalists and other esotericists dedicated to that ultimate locus of retribution. Alongside their concrete and abstract portraits of the Garden, these works discuss its relationship to the Godhead and the role it plays in personal eschatology, anthropology, and psychology. The book examines trends within the interpretive history of the biblical Paradise in medieval Jewish thought more generally, and in medieval kabbalistic literature in particular. The notion of gradations or distinct sites within the Garden of Eden is explored in light of its possible influences, and the appearance of the Garden of Eden within kabbalistic psychology is considered in light of thirteenth-century theosophical doctrines. A lengthy treatment is devoted to those works which delineate the architectonic structure of the supernal Garden and depict the visual appearance of the earthly temples (hekhalot) of the lower Garden, while mapping them onto the structurally complex interrelationships within the Godhead. Within this context, the book treats a number of textual conundrums concerning the very development of the kabbalistic canon, including the appearance of the Zohar. Throughout the book, the author also investigates scientific paradigms, legendary traditions, and theological polemics in the religious literature of the period concerning the appearance and structure of the Garden of Eden. Similar exegeses, shared traditions, and a common conceptual foundation of the eschatological Paradise are identified in the kabbalistic literature, alongside echos of the Jewish apocrypha, Rabbinic literature, and Hekhalot texts.

Thorough and meticulously researched, this study is based on a comprehensive reading of philosophical arguments drawn from all the major Jewish sources, published and unpublished, from the Geonic period in the ninth century until the dawn of the Haskalah in the late eighteenth century. The core of the book is a detailed discussion of the four doctrines of Christianity whose rationality Jews thought they could definitively refute: trinity, incarnation, transubstantiation, and virgin birth. In each case, Daniel Lasker presents a succinct history of the Christian doctrine and then proceeds to a careful examination of the Jewish efforts to demonstrate its impossibility. The main text is clearly written in a non-technical manner, with the Christian doctrines and the Jewish responses both carefully explained; the notes include long quotations, in Hebrew and Arabic as well as in English, from sources that are not readily available in English. At the time of its original publication in 1977 this book was regarded as a major contribution to a relatively neglected area of medieval Jewish intellectual history; the new, wide-ranging introduction prepared for this paperback edition, which surveys and summarizes subsequent scholarship, re-establishes its position as a major work.

The book discusses the development of the punishment theory of the Sages. The author traces the formulation course of this law by comparing a historical-philological study of Tannaitic writings and the writings of the Essenes sect .
